https://mechanicalsite.com/206/calculating-the-holding-capacity-of-a-hydraulic-pipe-clamp
<p>I am building a ground pushing and pulling probe similar to the pic attached. A probe rod is hydraulically clamped and held in place using a split clamp jaws that have a pyramid grip pattern made from hardened tool steel 58HRC similar to the pics. That paticular machine (in the picture) can hold upto 200kN of push/pull force. <strong>My question is how do I calculate the size and force of the hydraulic cylinder to hold a similar load 200kN?</strong> The jaws will be approx. 150mm high and match the dia. of the probe pipe which is 36mm 30-40HRC. The pyramid serrations will be as per the pic 1.2 x45deg.</p><p>Thanks for looking and any suggestion are much appreciated and welcome.</p><p>Thank you kindy.</p><p><img alt="" src="https://mechanicalsite.com/?qa=blob&qa_blobid=3053357210267291551" style="height:382px; width:600px"></p>Engineering Mechanicshttps://mechanicalsite.com/206/calculating-the-holding-capacity-of-a-hydraulic-pipe-clampWed, 19 Dec 2018 07:26:35 +0000Answered: position/alignment of a f/a-18 landing gear shock absorber

https://mechanicalsite.com/204/need-help-with-a-largest-axial-load-type-problem
<p>Hi, I'm a portuguese college student taking "Ortoprotesia" (our word for prosthetics+orthotics), which is basiccly a mix of health classes and mechanical and eletronic engineering classes, my "deformable systems" teacher, gave us this exercise and explained it.<img alt="" src="https://mechanicalsite.com/?qa=blob&qa_blobid=7765408651387039242" style="height:304px; width:600px"></p><p>I understood it and was able to solve it on m own by determinening the geometric ratios and finding the stress concentration factor from the slide, i then found the allowable average normal stress using the material allowable normal stress and the stress concentration factor, and then i applied the definition of normal stress to find the allowable load.<img alt="" src="https://mechanicalsite.com/?qa=blob&qa_blobid=1500802130302664375" style="height:291px; width:600px"></p><p>The teacher then gave us basiccly the same exercise but with a hole in the middle and told us to figure it out.<img alt="" src="https://mechanicalsite.com/?qa=blob&qa_blobid=10388684979536035620" style="height:299px; width:429px"></p><p>That's the part I'm struggling with, i looked around trying to find a similar problem, but i couldn't find any (partly because i don't know what to call this type of problem, axial loading with a hole? also, don't forget i'm portuguese and i'm not sure what the technical terms for a lot of these things translate to)</p><p>I would appreciate any help, either explaining me what to do / what to do diferently from the first problem, or directing me to some sort of website or video with a similiar problem.</p><p>Thanks in advance for any help.</p>Engineering Mechanicshttps://mechanicalsite.com/204/need-help-with-a-largest-axial-load-type-problemFri, 14 Dec 2018 15:39:33 +0000Answered: What is the mathematical expression of Lami's theorem?

https://mechanicalsite.com/55/what-is-stress
<p>When a object is subjected to loads it develops resisting forces. To find the resisting forces developed a section plane may be passed through the member and equilibrium of any one part may be considered.</p><p>Each part is in equilibrium under the action of applied forces and internal resisting forces. The resisting forces may be conveniently split into normal and parallel to the section plane.</p><p>The resisting force parallel to the plane is called <u><em><strong>shearing resistance</strong></em></u>. The intensity of resisting force normal to the sectional plane is called<em><strong> <u>intensity of Normal Stress</u></strong></em>.</p>Engineering Mechanicshttps://mechanicalsite.com/55/what-is-stressSat, 20 Oct 2018 20:10:43 +0000What are the assumptions in simple theory of bending?
